Hello!

The quadratic formula is

x =  \frac{-b + and - \sqrt{b^{2} - 4ac } }{2a}

the + and - means that for one solution you add them and for the other you subtract them

Hope this helps!

-376+-3=? <br><br>and how do i get my couculater to subtract negative numbers
nikitadnepr [17]
Well you could think of this like this
-376+-3, is the same as adding with negatives, instead of adding with positives, like 376+3, we are only changing the sign in front of it. So instead of it being equal to 379, -376+-3 = -379.

Please help I have no idea how to do this!!!
Ronch [10]

Answer:

You have to graph and label the points

Step-by-step explanation:

3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle

-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4

2 is just a horizontal line starting at (closed circle) 4, it is greater than also.

If you don't understand the the constants (the numbers on their own) just a vertical translation.

If the cross either the x or y axis, you have to find that too, im pretty sure.  

To find the y axis intercept, make x = 0 and solve for y

and to find the x axis intercept, make y = 0 and solve for x
